UTXO Stack is set to partner with Babylon to introduce a pioneering Bitcoin Layer 2 (L2) expansion solution, built on the native UTXO model. This innovative collaboration will feature a Proof of Stake (PoS) Data Availability (DA) chain, supporting challenge proofs for L2 constructed on UTXO Stack. Babylon will serve as the security provider, ensuring the integrity of both the PoS L2 and PoS DA chain.

This cutting-edge solution leverages a UTXO model akin to Bitcoin's, guaranteeing security through two robust mechanisms: user-staked RGB++ tokens and Babylon's remote BTC staking. By harnessing the power of these mechanisms, the solution aims to provide a high-performance environment with low transaction fees, supporting Turing-complete smart contracts. Users will benefit from the ability to pay fees directly using BTC wallets and BTC, streamlining the transaction process.

The collaboration between UTXO Stack and Babylon is poised to bring a highly efficient, low-cost, scalable, and secure native L2 solution to the Bitcoin ecosystem. This development is expected to significantly enrich Bitcoin's application scenarios, expanding its potential use cases. By launching its testnet in the third quarter of this year, UTXO Stack will enable staking and re-staking of assets like BTC and CKB, further solidifying its position in the market.

The partnership between UTXO Stack and Babylon demonstrates a shared commitment to driving innovation in the Bitcoin ecosystem. By combining their expertise, the two companies are set to revolutionize the way users interact with Bitcoin, providing a more seamless and efficient experience. As the cryptocurrency landscape continues to evolve, this collaboration is expected to play a significant role in shaping the future of Bitcoin.

The introduction of this native L2 expansion solution marks a significant milestone in the development of the Bitcoin ecosystem. By providing a secure, scalable, and efficient environment for users, UTXO Stack and Babylon are poised to unlock new possibilities for Bitcoin, further cementing its position as a leading cryptocurrency.
